Adaptive Beamforming for Antennas on General Wedge- and Cylindrical-Shaped Surfaces
(North Dakota State University, 2014)
Adaptive beamforming antennas capable of accommodating the growing number of wireless subscribers throughout the world has become an essential part of modern wireless systems. In this work, the beamforming of a conformal ...
Contextualization in Large-Scale Social Networks
(North Dakota State University, 2014)
Social computing-based applications provide a coherent medium through which people can be interactive and socialize by developing a Web-based communication channel that integrates different Social Networking Services (SNSs) ...
Zeroth Order Resonator (ZOR) Based RFID Antenna Design
(North Dakota State University, 2014)
Meander-line and multi-layer antennas have been used extensively to design
compact UHF radio frequency identification (RFID) tags; however the overall size
reduction of meander-line antennas is limited by the amount of ...
A Compact Cylindrical-Shape Microstrip Structure with Cloaking Properties for Mutual Coupling Reduction in Array Antennas
(North Dakota State University, 2014)
A cylindrical-shaped microstrip structure with cloaking properties is presented as a shielding device to reduce the mutual coupling between two patch antennas. The surface comprises of a number of 2-port microstrip (2-PM) ...
Fault Tolerant and Adaptive Systems with Focus on Networks-On-Chips
(North Dakota State University, 2014)
The first step in design of reliable systems is the ability to evaluate the reliability of the system. This is an important step in the process of designing reliable systems because design techniques that proactively improve ...
Network Convergence in Multicarrier Hybrid Cellular Network
(North Dakota State University, 2014)
In a multicarrier communication system with known channel state information at transmitter (CSIT), it is well-known that the water-filling power allocation scheme is optimal in achieving the Shannon capacity. However, in ...
Design and Analysis of New Printed Wideband Antennas for Wireless Applications
(North Dakota State University, 2014)
In this study a simple method to develop a wideband antenna is proposed. With this new technique a dipole antenna with a 48% frequency bandwidth is transformed to achieve a 120% frequency bandwidth for a voltage standing-wave ...
A Metamaterial-Based Multiband Phase Shifter
(North Dakota State University, 2014)
A design methodology for a multi-band phase shifter using a metamaterial-based transmission line was developed. This method is different in that the loaded-line phase shifter has a phase shift of 90 degrees at the center ...
Using Formal Methods to Validate the Usage, Protocols, and Feasibility in Large Scale Computing Systems
(North Dakota State University, 2014)
A paradigm shift has occurred in the Information and Communication Technology sector. The main obstacle to relegate complex and sensitive tasks is not the inadequate speed and unsatisfactory computing power of the existing ...
A New Methodology for the Design and Tuning of Robust PID Controllers in Electric Drives
(North Dakota State University, 2014)
AC induction motor-drive systems are the backbone for numerous industrial
applications, such as aerospace, medical equipment, and nuclear power plants.
The control performance of electric drives is sensitive to several ...
